back before I knew better.......I had ich. My tomini came in with it, and I could see some on all of my fish. Couldn't catch them out without dismantling the whole tank. So I soaked the food in garlic and fed them over a few hour period. Ich went away, came back a few weeks later (their hatching/lifespan as I understand it) but not as bad. Went away a few days later. 7 months later there has never been another sign. As I understand it if you can go a year or so without another outbreak the ich parasite will die-off. Not sure if I trust that or not. I'll probably hypo and definetly QT before I set up my next system.
